MACHINE FOR PREPARING IIIATERIAL FOR THE MANUFACTURE OF HAIR-FELT. HATS;

Application filed June 5,

To all whom it may concern:

Be it known that I, VVILLY Noaon, a citi- Zen of the German Republic, residing at Guben, Prussia, Germany, have invented certain nav and useful Improvements in Machines for Preparing Material for the lifianufacture of Hair-Felt Hats, of which the following is a specification. This invention relates to improvements in machines for blowing or cleaning fur, hair or the like adapted for use in the manufacture of felt hats.

This invention has for its principal objects to provide an improved means for uniformly feeding and evenly distributing loosened masses of hair into the initial blowing chamber of the machine, and at the same time freeing the admitted hair from relatively heavy admixtures of sand, pieces of hide, small shot, etc; to provide a succession of blowing chambers beyond the initial blowing chamber, together with perforate hair advancing drums for each blowing chamber adapted to cooperate with the feeding and picking rollers of the successive blowing chambers; said perforate hair advancing drums being adapted to permit the passage of air currents transversely theretln'ough, and deflector means being provided beneath said hair advancing drums whereby the air passing through the latter is deflected to produce a counter air current toward the picking roller of each blowing chamber, so that the separation of for eign materials and undesirable coarse hair is more thoroughly and rapidly accomplished.

Another object of this invention is to provide a novel arrangement and construction of blowing chambers adapted to retain the dust, consequent upon the hair blowing operations, within the machine and confined against discharge into the air of the workroom wherein the machine may be located;

Other objects of this invention, not at this time more particularly enumerated, will be clearly understood from the following detailed description the same.

In the accompanying drawings, Figure 1 shows a vertical longitudinal section of one embodiment of the novel fur or hair blowing and cleaning machine made according to the principles of this invention; Figure 1924. Serial No. 718,116.

2 is an end elevation of the same; and Figure 3 is a plan view of the same.

Similar characters of reference are employed in the above-described views, to IlI1-' dicate corresponding parts.

Referring to said drawings, the reference character 1 indicates the receiving bin or hopper at the receiving end of the machine, into which the hair or fur to be run through the machine is deposited. Access to the receiving bin or hopper may be had through a swinging door 2. Transversely disposed across the lower open end of said receiving bin or hopperl is a rotatable feed drum 3, which is provided upon its cylindrical surface with a plurality of outwardly projecting pins 4. Above the upper part of said feed drum 3 there is arranged a scraper plate 5 adapted to be'spaced concentrically a suitable distanceffrom the surface of said feed drum 3, and the front longitudinal edge of which is provided with a row of outwardly projecting take-off pins 6. Said scraper plate 5 is pivotally supported for transverse reciprocation above the surface of said feed drum 3 by means of supporting arms 7 which are fulcrumed on the axle of said feed drum 3. If desired, the supporting connections for said scraper plate 5 may be made adjustable so that the dis tance of said scraper plate 5 from the surface of the feed drum 3 may be variable, whereby the quantity of hair material taken up by said feed drum and conveyed into the machine may be regulated as desired. The reciprocation of said scraper-plate 5 is attained by means of rotatedcrank wheels 12, the cranks 9 of which are adjustably fixed in radial slots 11 with which said crank wheels are provided,.so that the stroke of said cranks 9 may be varied to in turn vary the limits of reciprocation of said scraper plate -5.' Said scraper plate 5 is provided at its ends with pivots 8, intermediate which and said cranks 9 are an ranged connecting rods 10 for translating the rotary movement of said crank wheels 12 into the desired reciprocatory movement of said scraper plate 5. Said crank wheels.

adapted to mesh with a gear 14 mounted on a second transverse driven shaft 15, to thus transmit operative movement to said crank wheels 12.

Fixed on the shaft 15 so as to be rotated thereby is a rotary comb plate 16, the opposite free longitudinal edges of which are provided with a plurality of comb pins 17, which are adapted to cooperate or mesh with the pins 4: of said feed drum 3 beyond the receiving bin or hopper 1, so as to remove or take off the hair material from the feed drum as the same is carried into the machine.

Disposed beneath said comb plate 16 is a rotating transfer roller 18 to receive the hair material removed from the feed-drum 3 by said comb plate 16. Said transfer roller 18 delivers the hair material to and between a pair of feeding-in rollers 19 and 20. Cooperating with said feeding-in rollers 19' and 20 is a rotating picking roller 22 which teases out, loosens and separates the fibers of the hair material fed forward by feeding-in rollers 19 and 20. Cooperating with the roller 20 is a scraper plate 21 which prevents the winding up of the hair material thereon, so that the latter is properly presented to the action of the picking roller 22.

The said picking roller 22 is located at the lower end of an upwardly extending channel or well which extends toand communicates with an initial blowing chamber 32. Arranged at the bottom of said channel or well 25 is a door 24 adapted to swing on a hinge connection 23. The door 24 opens to the atmosphere and thus permits air to enter the channel 25 below said picking roller 22. The rapid rotation of said picking roller 22 produces an upwardly rising current of air which passes through the channel or well 25 and into the initial blowing chamber 32. This upwardly rising air current carries the hair material upwardly into the initial blowing chamber 32, wherein the hair fibers are tossed, so that dust and dirt may drop by gravity out of the same. The tossed hair material decends at the forward side of the blowing chamber 32 upon a rotating perforate hair advancing drum 26. Said hair advancing drum 26 comprises a hollow cylindrical member, the walls of which may be made of coarse wire mesh, perforate sheet metal or the like so as to admit of air passing transversely through the drum, and so as to also permit dust and dirt to sift through the drum towards the closed under space of the machine which lies below the several blowing chambers.

Disposed adjacent to the forward side of said hair advancing drum, 26 are a pair of feed rollers 27 and 28 which receive the hair material advanced by the drum 26. Cooperating with the upper feed roller 28 is a scraper plate 29 to prevent the winding up of hair material on said feed roller 28. Cooperating with said feed rollers 27 and 28 is a rapidly rotated picking roller 30 which teases out, loosens and separates the hair fibers, and by reason of the upward air draft,-which is produced by its rapid rotation, tosses the loosened hair fibers upwardly into the succeeding blowing chamber 32, adjacent to the bottom open end of which said picking roller 30 is located. Also disposed in the bottom open end of said succeeding blowing chamber 32, and forwardly spaced beyond said picking roller 30 and opposite thereto is a rotating perforate hair advancing drum 31. The moving air current produced by the rapid rotation of said picking roller 30 is caused to pass partially upward into the interior of said succeeding blowing chamber 32 and partially against and directly through the perforate hair advancing drum 31 into the said closed under space of the machine. Extending beneath said hair advancing drum 31, so as to swing on a pivotal connection 34, is a deflector plate 33, which deflects the air passing downwardly through said hair advancing drum 31, so that said air is not permitted to discharge straight down into the under space of the machine, but is directed more or less toward and in proximity to the picking roller 30 as a counter stream against the main stream of air which is produced by the rapid rotation of said picking'roller 30. Said defiector plate 33 is adjustable toward and away from the underside of said hair advancing drum.

In hair blowing and cleaning machines it is generally the rule that a plurality of repetitions of the blowing processes are re quired to thoroughly loosen and clean the hair; consequently in the instant machine there are several successive blowing chambers 32 each equipped with feed rollers, picking roller, perforate hair advancing drum, and deflector plate beneath the latter, all arranged and related in the manner above described. In the drawings there are represented four blowing chambers succeeding the initial blowing chamber, but it will be understood that this number may be increased or decreased as may be ad visable under varying conditions relating to the use of the machine.

The means for supporting and for adjusting the deflector plates 33 beneath their respective hair advancing drums, comprises a frame 35 to engage and support the undersides of said deflector plates 33. Said frame 35 is mounted on eccentrics 36, which are fixed on shafts 37. Said shafts 37 are rotatable from a point outside of the machine, whereby the successive deflector plates 33 may be respectively set more closely to the perforate hair advancing drums of the suc cessive blowing chambers, in the manner shown in Figure 1 of the drawings, or, if desired, may all be equally spaced from the said hair advancing drums. The means for adjusting the said deflector plates is subject to more or less mechanical variation; consequently l donot limit myself to the specific means above described and as shown in the accompanying drawings.

The machine is provided with power transmission means for driving the Various rotatable elements thereof. As illustrated in the drawings said power transmission means may comprise the following or any equivalent 1nean s:

A drive shaft 39 is itself driven from any suitable source of power by pulleys 88. A driven shaft 42 is provided having a pulley l1 driven by a belt from a pulley 4:0 fixed on said drive shaft 39. The shaft i2 is provided with a graded or variable speed pulley 13 which drives, through abelt, another graded or variable speed pulley set which is fixed on said shaft 15, to thereby rotate the latter and the comb plate 16 mounted thereon. The shaft is provided 'vith the heretofore mentioned gear 14; which meshes with the teeth of one of said cranlr'wheels 12, to thus rotate said crank wheels and thereby actuate the connecting rods 10 to provide operative reciprocation of the scraper plate 5. The shaft 15 is also provided with a gear which meshes with and drives a gear 46 for rotating the lower feeding-in roll 19. Iiitei'nie'shingg spur gears or pinions i? and 4.8 respectively mounted on the journals of said feeding-in rollers 19 and 20 serve to actuate the upper feeding-in roller 20. In like manner the opposite ournal of said feeding-in roller 19 is provided with a gear or pinion 4'9, which meshes with and drives a gear 50 mounted on the adjacent journal of said transfer roller 18. Secured upon the opposite journal of said transfer roller 18 is a sprocket wheel '51 which drives a chain 52 whichruns over a sprocket wheel 53 fixed on the shaft of said fee-d drum 3, thus actuating the latter.

Secured upon the drive shaft 39 is a drive pulley 5% which drives, through a belt, a pulley 55 which is fixed on the shaft of said picking roller 22. thus producing the operativcrotation of the latter. The picl'ring' rollers 30 are driven partly from the drive shaft 39 and partly from a lay shaft. 55, said shafts having pulleys '56 for a transmission belt. On each shaft 39 and 55 is a pulley 56 which drives, through a bolt, the pulleys 57 respectively fixed on the journals of said respective picking rollers 30.

The means for driving thetgroups of feed rollers 27 and 28 and the several hair advancing drums 26 and 31, comprises a gear and shaft transmissio'ii which receives its motion from a driving bevel gear 58 mounted on an end of the shaft 42. Journaled in a bearing bracket 60 is a vertical spindle provided at its lower end with a bevel gear 59 which meshes with and is driven by said bevel gear 58, and at its upper end with a bevel gear 61. Supported in suitable bearing brackets, so as to extend long-L tudinally along a side of the machine, isfa shaft 63 upon which is fixed a bevel gear 62, which meshes with and is driven by bevel gear 61. The lower feed rollers 27 are driven by intermeshi'ng bevel gears "64: and 65 respectively mounted on said shaft 63 and the journals of said lower feed roilers. The upper feed rollers 28 are driven by intermesh'ing spur gears '67 on the respective journals of said upper and lower feed rollers 27 and 28. The fdisch'arging rollers 7 2 and 73, which are adjacent toth'e iair advancing drum of the last blowing chamber 32, are driven in manner and by means similar to that above described for driving the feed rollers 27and 28. Said discharge rollers 72 and 73 serve to deliver the cleaned hair out of the discharge end of the machine. The hair advancingdrums 26 and 31 are driven by intermeshing spur gears 68 and 69, said spur gears 68 being idler gears driven by the gearing 67, and transmitting motion to the spur gears 69 which are respectively fixed on journals of said hair advancing drun'is 2i) and 3 1.

V'Vhen in use, the machine constructed according to the principles of this invention, functions as follows The hair material to be cleaned is deposited in bull: within the receiving hopper or bin 1. As the hair descends to the bottom of the receiving hopper or bin it it en gages the rotating: feed drum 3, the a jectin'g pins 4 on the surface of whirh tend to ,gripth'e hair so that the same carried forward and out of the bottom of the receiving hopper or bin for introduction into the interior of the machine. It is big y desirable that a continuously entering uniform quantity of hair be fed into the machine, to the end that the blowing and cleaning functions may be most eliiciently attained, without choking or overloading the machine. To this end an automatic feed control, cooperative with the feed drum 3, is provided to automatically regulate and control the quantity of hair delivered into the machine by said feed drum. This automatic feed control comprises the recipro eating; scraper plate'5, which is caused to move back and forth over the forwardly rotating surface of the feed drum 3. Said scraper plate 5 is set or adjusted in desired spaced relation to the surface of the feed drum, so that only "a heat or layer of hair of predetermined "thickness, and there fore of predetermined quantity, can be "carto prevent further deposit of hair upon the latter, while at the same time the projectmg take-off pins 6 of the free edge of the scraper plate 5 will comb or take off any hair in excess of the thickness of mat or quantity thereof desired to be entered in the machine. By setting the scraper plate closer to or further away from the surface of the feed drum 3, the quantity of admitted hair may be decreased or increased as may be advisable. This automatic feed regulation means of the machine is one of the important novel features of the present invention.

After the hair passes out of the hopper or bin 1 it is carried. forward by the feed drum 3 toward the rotating comb plate 16, the pins 17 of which, by intermeshing with the pins 4 of the feed drum, serve by their movement to disengage the hair from the latter, whereupon said hair drops down upon the transfer roller 18. The transfer roller 18 by its movement conveys the hair to the receiving side of the feeding-in rollers 19 and 20, which feed the hair forwardly into engagement with and subject to the teasing, loosening and separating action of the rapidly rotated picking roller 22, whereby the hair fibers are substantially loosened and separated one from another. The rapid rotation of the picking roller 22 produces an ascending air current at the far side of the same, which tends to rise upwardly through the channel or well 25 and thence into the initial blowing chamber 32. The lighter hair fibers tend to follow and ride upon said ascending air current, and are consequently tossed upwardly within the initial blowing chamber and by the process are further loosened and separated, so as to permit dust, dirt and undesirable relatively heavy admixtures to separate and drop away therefrom. Owing to the centrifugal action involved in the movement of the hair material by the picking roller 22, the comparatively heavy admixtures of sand, pieces of hide, small shot, and coarse undesired hair fibers and tufts, tend to be thrown clownwardly toward the bottom of the channel or Well 25, to pass thence through the bottom opening or slot provided by the partially opened door 24 at the bottom of said channel or well, thus almost immediately effecting a thorough separation of undesired admixtures contained in and among the relatively light or fine hair fibers it is desired to conserve, loosen and clean. The light hair fibers without substantial loss or waste are tossed into the initial blowing chamber 32 by the ascending air current as aforesaidso as to rise upwardly therein until the diminishing force of said ascending air current permits gravity to act upon the hair fibers, which thereupon tend to descend within the far side of the initial blowing chamber 32 so as to be received by or upon the slowly forwardly rotating hair advancing drum 26, and thereby conveyed to the receiving side of the feed-rollers 27 and 28.

The feed rollers 27 and 28 convey the hair fibers forwardly into engagement with and subject to the further teasing and separating action of another rapidly rotated picking roller 30 disposed in the lower open end of a succeeding blowing chamber 32. The rapid rotation of the picking roller 30 also produces an air current which moves both toward the adjacent perforate hair transfer drum 31 (which is spaced forwardly from and opposite to said picking roller 30) and upwardly into said succeeding blowing chamber 32. The centrifugal force produced by the rapidly rotated picking roller 30 tends to cast downwardly into the bottom or under space of the machine remaining undesirable admixtures and coarse hair fibers and tufts, so that the separated lighter or fine hair fibers which it is desired to conserve and clean are further relieved from such undesirable admixtures, and are again A tossed upwardlyinto the succeeding blowing chamber 32 to be further loosened and separated. Owing to the fact that the hair advancing drum is formed by a perforate hollow body, that portion of the air stream, produced by the picking roller 30, which flows toward said hair advancing drum may pass transversely thereinto, and is not dissipated downwardly into the under space of the machine, and thus permitted to carry with it, and consequently to waste, lighter hair fibers which it is desired to conserve. The air thus passing transversely into the interior of the hair advancing drum may pass downwardly and out of the same, but upon emerging impinges upon the underlying deflector plate 33, whereby the same is deflected back toward the picking roller 30 as a counter current of air. The centrifugal force exerted upon the hair material by the picking roller 30 is such. that the heavier or undesired coarse hair fibers or tufts tend to more quickly fiy out of the influence of the air stream than do the lighter hair fibers, which tend to more readily follow the movement of the air stream. As a consequence of these tendencies, the counter air current will engage the coarse hair fibers, which tend to fly out of the main forwardly and upwardly flowing air stream, and will retard their movement in the latter, thereby assisting the same to more readily and quickly separate themselves from the desired lighter hair fibers and thereupon deposit themselves in the underspace of the machine.

The above described hair blowing and cleaning operations may be successively repeated by employing a series of succeeding blowing chambers 32 equipped with picking rollers 30, hair advancing drums 31 and feed rollers 27 and 28, as shown, until the thoroughly loosened and cleaned hair is finally discharged from the machine by the discharging rollers 72 and 73.

By properly adjusting the deflector plates 33, the force of the counter currents ofair produced thereby may be more or less strongly opposed to the main forwardly and upwardly moving'air streams which are directed into the blowing chambers 82, ac: cording to the degree or extent it is desired or necessary to remove relatively coarse hair fibers, etc, from the hair material. The more closely the deflector plates are set towe d the hair advancing drums, the more the counter currents of air be directed so to join the upward movement 01" the main air streams into the blowing chambers above, and consequently the less will be the separating effect upon the hair material traveling in said main air streams; while the further (within reasonable limits) the deflector plates are spaced from the hair advancing drums, the more strongly will the counter currents of air be opposed to the main air streams, and consequently the greater will be the separating elitect u Jon the hair material traveling in the latter. This being so it is usually advisable, when a series or plurality of successive blowing chambers 32 are provided, to successively diminish the space between the respective succeeding dc rector plates and the hair advancing drums to which they are opposed toward the di charge end of the machine, in the manner indicated in Figure l. of the drawings.

it will be readily apparent that the machine is provided with closed blowing chambers and a closed underspace, and that con,-

sequcntly the dust, incident to the cleaning of the hair material, will be retained'entira ly within the machine, therefore the ma: chine, in operation, does not diminish the sanitary condition desired .in the work room wherein may be located.
